Hope your HW was turned on to gas as on elec w/o water can easily burn the anode...
I'm not sure what else I can do with the hitch setup.. I've tried keeping the truck level, and tried adding more weight to the rear, and both had the same effect. I read in the towing section people saying it could be caused by bad shocks, and mine are 7 years old. So I figure if I have to replace something air bags might be better?
My water heater is only gas as far as I know. I didn't see a switch in there to turn electric on or off. Luckily it was unfounded worry... I was afraid it hadn't filled, but it had. Now I know how to check and see if it is full before turning it on atleast.
